haha...thanks Neil!
Well, as the gf wasn't around this weekend, i thought i'd persevere with this little project...
So i took some advice from the guys on detailingworld and also got myself some wire wool and autosol.
I must admit that despite a lot of effort, it only improved it marginally and the grime on the inner tips just wouldn't come off.
I also tried using 1000, 800 and 400 grit....It's really taken me by surprise how stuborn exhaust gunk can be when left untouched for years.
In the end, i bough a very light sandstone head to slowly grind away at the areas i wasn't able to clean. Even with this, it still took me 2 hrs to get the finish i have now and there are still some areas that I haven't been able to get off.
I just totalled the hrs that i've spent on this so far and it's looking like almost 6 hrs so I'm going to leave it there....i pretty pleased but was hoping the inner tips would come up a bit better. I may give it another go in the summer when it's not so frickin' cold!
All i gotta do now is fit it...if it would only stop snowing! lol!

PS - apologies for out of focus pics...crummy iphone camera tends to focus on the background.
The bit i'm less pleased with...but I can live with
